Quick coupler

ABSTRACT

A quick coupler has a coolant supplier seat and a transmission seat that can be optionally connected or disconnected. When the coolant supplier seat is connected to the transmission seat, the coolant can flow automatically from the coolant supplier seat to the transmission seat, so as to cool down electronic components inside a rack. When the coolant supplier seat is disconnected from the transmission seat, the coolant instantly stops flowing into the transmission seat. Because of the quick coupler, the rack installed inside a narrow space is convenient to set up or disassemble.

1. Field of Invention

The present invention relates to a quick coupler, and more particularlyto a coupler structure that enables a mount and a coolant supplier to bequickly disconnected and connected without consuming excessive laborwork or labor time.

2. Related Art

Liquid-cooling heat-dissipation is widely applied in heat dissipation ofelectronic products. In an existing liquid-cooling heat-dissipationdevice, pipelines are fixed in an electronic product and then connectedto a coolant supplier.

The coolant supplier provides coolant to electronic components whichneed heat dissipation within the electronic product via the pipelines.Thus, heat exchange occurs between the coolant and the electroniccomponents, so as to realize heat dissipation for the electroniccomponents. Then, the coolant which is heated due to the heat exchangeflows back to the coolant supplier and is further cooled down, so as tobe used again for next heat exchange.

However, in the above liquid-cooling heat-dissipation device, thestructure thereof still has disadvantages in practical use. As thepipelines are fixed, if the electronic device is configured densely, forexample, a plurality of servers is configured within a fixed space, itcan be imaged that too much labor time and labor work are consumed whenthe pipelines are being connected to or disconnected from the coolantsupplier, and a lot of troubles and inconveniences are causedaccordingly.

The bearing pillar 43 has a first hole 430 and a second hole 431 atpositions respectively corresponding to the fluid outlet hole 32 and thefluid inlet hole 33. The bearing pillar 43 has a liquid flow-out hole432 and a liquid flow-in hole 433 in a periphery thereof at positionscorresponding to the fluid outlet hole 32 and the fluid inlet hole 33.The liquid flow-out hole 432 is communicated with the first hole 430,and the liquid flow-in hole 433 is communicated with the second hole431. The bearing pillar 43 is sleeved with a leak-proof washer 434, soas to generate a better sealing effect between the bearing pillar 43 andthe recess 30.

The two flow retaining pillars 42 are respectively disposed in the firsthole 430 and the second hole 431, and used for optionally sealing thefirst hole 430, the second hole 431, the liquid flow-out hole 432, andthe liquid flow-in hole 433. An end of each elastomer 41 pushes againstthe bearing blade 40, and an other end of the elastomer 41 pushesagainst the corresponding flow retaining pillar 42. The elastomer 41 maybe a spring. The flow retaining pillars 42 are sleeved with leak-proofwashers 420, so as to generate a better sealing effect between the flowretaining pillars 42 and the first hole 430 and the second hole 431.

Referring to FIG. 4, the coolant supplier seat 1 may be connected to onecoolant supplier, and the transmission seat 3 may be connected to a rackhaving electronic components that need heat dissipation. When thecoolant supplier seat 1 is connected to the transmission seat 3, thepositioning pillar 12 is inserted into the positioning hole 31, so thatthe transmission seat 3 and the coolant supplier seat 1 are wellpositioned and connected to each other.

An end portion of the stop pillar 24 is pushed against by the bearingpillar 43, so that the stop pillar 24 is withdrawn into the tank 10, andcompresses the elastomer 23. An end of the flow-in tube 21 having theoutlet holes 211 is inserted into the first hole 430, so that the flowretaining pillar 42 located in the first hole 430 is withdrawn into therecess 30, and compresses the elastomer 41, so that the outlet holes 211are communicated with the fluid outlet hole 32.

Coolant at a low temperature from the coolant supplier flows through theflow-in hole 15, the inlet hole 210, the flow-in tube 21, the outletholes 211, the liquid flow-out hole 432, the fluid outlet hole 32, andthe fluid outlet tube 341, so as to reach the electronic components thatneed heat dissipation, so that heat exchange occurs between the coolantand the electronic components. Thus, the electronic components dissipateheats and are cooled down, and then after the heat exchange, the coolantturns into coolant at a high temperature.

The coolant at a high temperature flows through the fluid inlet tube340, the fluid inlet hole 33, the liquid flow-in hole 433, the inletholes 221, the flow-out tube 22, the outlet hole 220, and the flow-outhole 16, so as to flow back to the coolant supplier, so that the coolantat a high temperature is cooled down to become coolant at a lowtemperature, which is used for next heat exchange.

When the rack needs to be disconnected from the coolant supplier, thecoolant supplier seat 1 and the transmission seat 3 are directlydisconnected from each other, and then the compressed elastomers 23 and41 respectively force the stop pillar 24 and the flow retaining pillars42 to return to the initial positions, and the stop pillar 24 seals theoutlet holes 211 of the flow-in tube 21 and the inlet holes 221 of theflow-out tube 22, and the flow retaining pillars 42 seal the first hole430, the second hole 431, the liquid flow-out hole 432, and the liquidflow-in hole 433, thereby stopping the flowing of the coolant, andpreventing leakage of the coolant when the rack is disconnected from thecoolant supplier.
